Improvements in reliability assessment and prediction methodology

This paper describes the continuing evolution of Honeywell's HIRAP, Honeywell In-Service Reliability Assessment Program. The approaches used in HIRAP remain consistent with industry efforts in the area of reliability assessment. The paper also presents a description of the process flows, showing simplifications that have occurred in the process over the last year. Unlike conventional reliability prediction methodologies, which focus solely on part failure rates, the methodologies presented here incorporate design failure rates, manufacturing process failure rates and other causes for equipment removal.
